Ton/ZZ whom it may concern,.- y

Be it known that I, FRANK'MoMURR-AY SAWYER, a citizen of the UnitedStates, re

sidingat Charlotte, in the county of Mecklenburg and State of NorthCarolina,.have invented certain new and useful Im rovements inMolds andI do declare the fol owing to be a full, clear, and exact description oftheinvention, such as will enable others skilled in the art to which itappertains to make and My invention is an improved moldfor moldingrooiing-tiles and other like articles; and

- it consists in the construction, combination,

and arrangement of devices hereinafter described and claimed.

The object'of the invention is to provide an improved mold of thischaracter which is adapted for molding a number of tiles simultaneouslyand the parts of which are adapted to be readily assembled andseparated.

In the accompanying drawings', Figure l.

' is a top plan view of a mold embodying Vmy improvements.- Fig. 2 is adetail top plan view of the same. Fig. 3 is a similar view showing amodification, and Fig. 4 is a similar view showing another modificationIn the embodiment of my invention I provide a suitable number oflongitudinal moldpieces 1 and of transverse mold.- pieces 2. Thelongitudinal pieces are here .shown as boards, and they are connectedtogether by cross-bars 3, which are detachably secured thereto. `Anysuitable means may be emloyed for detachably connecting the longituinalpieces 1 together, andI do not desire to limit myself in thisparticular. Furthermore, any suitable 'number of longitudinal pieces maybe employed, according to the desired capacity of the mold.` Betweeneach pair of longitudinal pieces 1 are placed a plurality of thetransverse moldieces `2. The same aremade of sheet-stee orany othersuitable metal, are bent or shaped according to the size andshape of thetiles or other articles to,be molded between them, and are arrangedv inparallel relation and. suitably' spaced apart, as shown. Thelongitudinal pieces are formed on their opposing sides with verticaltransverse corrugations or notches Y or flutes 6, which may be of anyrequired form, according to the character of the trans l versemo1dpieces,.and of the form of the of the transverse pieces, so that thesaid. notches, corrugations, or flutes serve to appropriately space thetransverse pieces a art and to also form the side edges of the mo dedarticles. The-corrugations, notches, or flutes are formed by detachablestrips or pieces 7, which may be of metal, bear against the longitudinalpieces, are fitted between the transverse pieces, and are -`held inplace by the angles 14, formed in the transverse pieces near their sideedges.

In the form of my invention shown in Fig. 2 the .said detachable stripsor pieces 7 are of oblongrectangular form 1n cross-section.

In the form of my invention shown in Fig. 3 the detachable strips 8 aremade of sheet metal, bent to form right-angular surfaces 9 .'10 torespectively lie perpendicular to the ing also formed withoutwardly-extending.`

flanges 1l, which engage the outer vedges of the transverse pieces.

In the form of my invention shown in Fig. 4 the detachable, strips 12are of substantially triangular form in cross-section and are eachprovided on one side with a-rabbet 13 to receive the side edge of one ofthe-transverse f plates or pieces.

Having thus described myinventiomwhat I claim as new, and desire tosecure by Letters Patent, is-

The herein-described mold comprising the side pieces, the transversepieces between the side pieces and having their sides bent to formangular osets at their edges, and the detachable strips on the innersides of the side pieces, lying between and spacing the transversepieces and bearing against the anguiar odset portions of saidtransversepieces and held in place thereby.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. Y
